I figure this will probably be Payton Manning's last game. He's had a hell of a career, and to go out on top is what players want to do.
As a side note - if there's one celebrity I look like, it's Payton Manning. I've actually been accosted by people who thought I was him, until they got up close and found out that I was a few inches shorter. So, when he retires, there will be nobody famous who looks like me. Bummer.
